Intelligent power distribution – All-wheel drive

Intelligent power distribution – In many cars, the drive is electronically controlled, which allows better separation of torque between wheels. Some systems, as in the case of the Haldex system, redirect drive to the second axis when the sensors catch the slip.
In others – as in the xDrive system in BMW – the drive hits both axles. In normal conditions, i.e. when the grip is good or very good, 40% of the drive is directed to the front and the rest to the rear – BMW thus behaves typically sports characteristics. Torque, through a multi-plate clutch with a suitable control computer. It can be easily and continuously distributed in xDrive between axles – up to 100%, only for two wheels.
In Subaru, the drive was driven with semi-axles driving the wheels, which are the same length. This “symmetry”, according to the Japanese, greatly improves the confidence of running on curves, especially on slippery surfaces.
